8.关于日期格式 [%U(l<

日期格式设定 Ap}^6_YXd

9.获取错误信息并到指定页面 m/#)B6@A
T7f>u}T
不要使用Response.Redirect,而应该使用Server.Transfer IipG?v0z~
e1'<;;; L
e.g nS xFz!
// in global.asax l7G&[\~
protected void Application_Error(Object sender, EventArgs e) { o&2(xI2
if (Server.GetLastError() is HttpUnhandledException) i7h!,vaK
Server.Transfer("MyErrorPage.aspx"); 6FMW}*6<
x!CCSM;q
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) #KA,=J
} ?)=A[
]Lg$p
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 N?`-$C ]
